The GCMD is very active within the ESIP community and regularly attends the summer and fall meetings. The GCMD has provided a customized ESIP data portal and ESIP
services portal to search for data and services holdings from ESIP members. In addition, GCMD staff members participate in the following committees: (1) Information Technology and Interoperability; (2) Products and Services; and (3) Preservation and Stewardship.

U.S. Government
Federal Agency Collaborations

National Oceanic
and Atmospheric Administration (NOAA)

GCMD continues close collaborations
with NOAA through the exchange of metadata
information. The GCMD is a participant
in the NOAA
Operational Model Archive and Distribution
System (NOMADS) program and has
contributed a custom
portal for model output data sets. Numerous metadata records have been exchanged with the NOAA National Geophysical Data Center (NGDC) and the National Climatic Data Center (NCDC) using the OAI-PMH standard.

The
CEOS IDN
is an international effort to assist researchers
in locating information on available data
sets. The GCMD shares information with
other CEOS IDN nodes throughout the world
and also provides software, search interfaces
and metadata writing tools.

The GCMD serves as the database for the Global
Ocean Ecosystems Dynamics Project (GLOBEC) metadata. As noted on the GLOBEC site, after the completion of the project in 2010, it is intended that the GLOBEC metadata be included in the Global Change Master Directory (GCMD) database to ensure long-term stewardship. The GLOBEC data sets are available through
the GCMD and a GLOBEC
portal.

The Ocean Biogeographic
Information System (OBIS)

The Ocean
Biogeographic Information System (OBIS)
is the information
component of the Census of Marine Life
(CoML). It is a web-based provider
of global geo-referenced information on
marine species. Marine species data
collections from all of the world's oceans
can be discovered through the
OBIS portal.

International Polar Year
(IPY)

The International Polar Year is a scientific programme focused on the Arctic and the Antarctic from March 2007 to March 2009. The GCMD continues to support the International Polar Year's worldwide effort in the data and information management of IPY.

Global Earth Observation System of Systems (GEOSS)

The Global Earth Observation System of Systems (GEOSS) is an international
effort to monitor the Earth for societal benefits and sustainable
development. GCMD continues to coordinate with the global community of international (e.g. CEOS International Directory Network), intergovernmental, and regional organizations providing solutions for the 10-year GEOSS Implementation Plan.

Portal Collaborations

GCMD
has recognized the importance of customization of the search site
for partner organizations and is generating
subset views of the Directory through
portals. Portals have made it easier for
organizations to maintain and document their
data in one place without duplicating the
effort to create another online directory. To access portals and to learn more, visit: http://gcmd.nasa.gov/add/portals.html
